This mistress was training her athlete to build endurance and to also be prepared for an upcoming competition. But since they did not know each other well, the athlete did not think much of his trainer. But she surprised him by choke holding him and making him smell her sweaty armpits before he begged her to let him go, something she did not do immediately so that it could be punishment for him.
Madame Marissa is a very private person. When she realized that her slave had leaked her secrets to someone, she was pissed off and had to make sure he learned his lesson. She beat him up by kicking him and using her feet to crush his neck and choke him. She had not used her martial arts skills to beat up someone in a while so it was refreshing and a lot of fun for her.
Madame Marissa wanted to toughen her slave. She made him remove his shirt and had fun kicking him and trying her mixed wrestling skills on him. She kicked him and even used her feet to choke him.
